Changed implementation to strip tokens up until the first 'Size: '
string. This will allow for less parsing errors in the first
six lines of the following output:
"dmidecode --type 17 | grep Size" returns:
Maximum Memory Module Size: 4096 MB
Maximum Total Memory Size: 8192 MB
Size: 2048 MB
Size: 2048 MB
Added a condition in the exception handling to address the
issue of the bug on other outputs like:
Installed Size: Not Installed
Enabled Size: Not Installed
Size: No Module Installed
Size: 1024 MB
Common strings like "No Module Installed" and "Not Installed" are
normal. These two strings are hard coded in the before mentioned
comparison and when found are logged as warnings instead of errors.
